Solution Overview

Problem

The increasing demand for wireless communication access points requires a large number of antenna masts, which poses challenges in public acceptance due to the need for additional functions beyond supporting antennas, leading to complex and costly manufacturing and installation processes.

Innovation Solution

A modular antenna mast system comprising a set of interchangeable lower and upper modules, allowing for the integration of various devices such as traffic lights, electronic screens, or waste bins, to provide additional functions while supporting the antenna arrangement, thereby enhancing flexibility and public acceptance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a number of antenna masts are provided with different further functions to maintain public acceptance in restricted areas, then public acceptance is improved, but manufacturing and installation complexity and cost increase

Engineering Contradiction:
Improvepublic acceptanceVSAvoidmanufacturing and installation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a standardized mast body that can accommodate multiple different devices (traffic lights, street signs, benches, waste bins, lighting arrangements) through interchangeable mounting mechanisms. This allows a single mast design to serve multiple functions across different locations, improving public acceptance without requiring complex custom manufacturing for each location.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the mast system into a standardized mast body component and separate interchangeable devices. This segmentation allows the mast body to be manufactured once in standard configurations, while different devices can be attached as needed, reducing manufacturing complexity while maintaining versatility for different public acceptance requirements.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If different further functions are integrated into antenna masts, then public acceptance is improved, but manufacturing cost increases

Engineering Contradiction:
Improvepublic acceptanceVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The standardized mast body design with universal mounting mechanisms allows the same base structure to support multiple different devices. This reduces manufacturing costs by eliminating the need to create entirely different mast designs for each device type, while still providing the adaptability needed for public acceptance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent incorporates pre-designed mounting interfaces and attachment mechanisms during the initial mast body manufacturing. This preliminary action allows devices to be easily attached later without requiring complex custom fabrication, thereby reducing overall manufacturing costs while maintaining the ability to provide different functions.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method of providing an antenna mast for a wireless communication system is presented. The method comprises selecting a lower module and an upper module from a set of modules. This set of modules comprises at least two different lower modules, at least two different upper modules, or at least two different lower modules and at least two different upper modules. The method further comprises assembling the selected lower module and the selected upper module into a mast body of the antenna mast. This mast body forms a supporting structure for an antenna arrangement of the wireless communication system. In assembling the mast body, the method includes the antenna arrangement in the selected upper module and includes in at least one of the selected lower module and the selected upper module a device configured to perform a function other than supporting the antenna arrangement.
